Exodite is correct- the crossbar is too sensitive and hard to use. Given that other buttons are represented (play, ff, etc) why not represent the up down, left right and center buttons as well. The crossbar seems a needless gimmick. The app connected with by BD player just fine though- ( you must REGISTER each device) makes for a good companion to a streaming media server like "twonky" - using these apps together makes a quasi "Airplay" for the android.
Note to Sony app people- please fix the crosshair!
